The utility model provides a local weighing system of thing rejects which characterized in that: include buffer memory device (1) connected according to the preface, weighing device (2), material feeding unit (3), control system (4) respectively with buffer memory device (1), weighing device (2), material feeding unit (3) are connected, buffer memory device (1) and weighing device (2), the flexible flange of adoption is connected between weighing device (2) and the material feeding unit (3). According to claim 1 a local weighing system of thing rejects, its characterized in that: lower extreme at buffer memory device (1) is equipped with self -acting valve (5), weighing device (2) are adopted weighing sensor (6) and are weighed, are equipped with self -acting valve (7) at weighing sensor (6) lower extreme. The beneficial effects of the utility model are that, made things convenient for statistics offal, stalk bamboo slips etc. To reject the volume of thing, can more accurately calculate tobacco leaf, the waste of offal in whole processing, transport flow, realized weighing in this locality of rejection things such as offal, stalk bamboo slips, filled the domestic gaps.
